6 month old poop

Marie • Hello, my name is Marie, I'm 27 years old and I joined this website the moment I found out that I was pregnant. This is my first pregnancy and I'm praying for a 100% healthy baby boy or girl 😊
Just a brief story so my son is 6 months and for the first 6 months I did 50/50 breastfed and give him formula now I give him strictly formula and I'm realizing that every single time he drinks he's pooping his doctor said that he's gaining weight, so it's nothing to worry about but do you think I should take him to an allergist to see if he has a milk allergy. He's popping about 4/5 times a day im so sad
